Is there any way thus far of combining THREE or more archetypes into a single build?

I initially tried doing that but I'm not sure how I'd showcase it. After I finish doing 2 Archetypes, I may go back to double check for Triples.

As Curious said, Quingong is the go-to for 3 archetypes, though Totem Warrior will always plus one any Barbarian mix. I don't even know why it's listed as an archetype, since it doesn't actually change anything besides giving fluff text.
